PURPOSE – To methodically lead and execute a RCFA “root cause failure analysis” to uncover the actual cause of equipment failure using a defined process, facts data and logic. If the proper “root cause” is identified the goal is to prevent a reoccurrence of the failure and to develop the proper corrective action steps. RCFA: the typical path for traditional root cause discovery and analysis begins with the discovery of a problem and ends with recommendations to solve the problem. A variety of techniques, both informal and structured, that can be used to determine these causes. This should complement reactive or proactive PES opportunities.

(Internal Offer Sheet: Place holder when available)

|LOCATION |JOB STEPS |

|Home office (Pre-Planning) |Identify the problem to be solved |

| |Write a goal statement. What are we trying to accomplish? |

| |Determine members of the RCFA Team. |

| |Develop a communication plan both internal and external. |

| |Communicate with the customer on availability and timeline for a site visit to interview key personnel and |

| |physically look at the suspect equipment. |

|Customer site/where equipment is located |Step 1: Collect Base line Information (records and onsite physical inspection) |

| |Identify Unit(s) or components for inspection. |

| |Determine operating sequence of component. Review Tech Manual “operations and maintenance” sections to |

| |understand machine operations and maint requirements. |

| |Record operating conditions, environment. |

| |Develop IPP (Incident Process Plot) with customer to develop map and timeline of events. |

| |Record hours on equipment, components, and lubricant. |

| |Schematic of equipment, access to operation maintenance manual. |

| |Review current maintenance practices included oil analysis results, oil drain interval data, filtration |

| |information (with possibility of gathering deposits) and equipment rebuild history, replacement parts OEM or |

| |non-OEM or remanufactured parts, installation techniques, equipment storage, etc. |

| |Determine to whom results are reported what level of responsibility to take action. |

| |When possible determine TCO components that apply. |

| |Frequency of incidents. |

| |Step 2: Assemble Toolkit |

| | |

| |Ensure camera is in working order. Second battery. |

| |Determine if power source is needed or available. |

| |Refer to JSA for all Safety items/PPE. |

| |Clipboard or other appropriate documentation gathering systems. |

| |Flashlight and batteries. |

| |Step 3: Planning the Study |

| |Discuss and gain approval from station personnel all equipment and any hot work permits that will necessary |

| |to conduct the inspection. |

| |Schedule the event, and review any necessary safety precautions JSA’s (i.e. lock out tag out for gas, |

| |electrical, steam, water, etc.) |

| |Determine the availability of power. Not all sites have electricity. Have customer provide power sources |

| |for any equipment necessary for dis-assembly or re-assembly of machines. |

| |Arrange for mechanic to assist. |

| |Review any previous inspection data. |

| |Step 4: Conducting the Study |

| |Ensure unit has been down and cooled. |

| |Ensure unit is ready to be inspected. |

| |Disassemble all parts for inspection. |

| |Gather any additional deposits, oil or parts for further lab analysis. |

| |Understand process, environment, operating conditions. |

| |Note equipment and component. Operating temperatures, lubricant in use, etc. |

| |Take photographs in sequence. Orient part so load zones can be identified. |

| |For engines, label components by cylinder number. For industrial applications, label multiple components by |

| |unique ID or orient them by direction. |

| |Start from one end and the process and look for deviations in operations and performance from records and |

| |interviews of mechanics and operators |

| |Ensure you contact customer immediately of any significant abnormal conditions identified. |

| |Remove lock out tag out lock and identifier. |

| |Review immediate findings with customer. |

| |For situations where product quality is questioned, obtain C of A and secure shipment retains for LTS |

| |analysis. Gather batch numbers for checking manufacturing up line. Obtain retain samples from deliveries. |

| |Ensure to follow proper sampling procedures. Ensure to follow instructions for proper use of LTS (including |

| |sample labeling for potential sample hazards that might be posed to the LTS lab – e.g. ammonia from a |

| |refrigeration unit). LTS Portal Link |

| |Use OEM and other equipment/component failure guides to assist with abnormal condition (wear, deposits, etc.)|

| |observed. |

| |Using the Casual Factor Analysis tool take the direct causes identified in the IPP and ask “why” they took |

| |place three to five times until you have reached a conclusion that uncovers the root causes. |

| |Ensure you have good data (pictures, reference wear patterns that correlate to observed customer equipment, |

| |used oil analysis/other LTS data, etc.) to support the direct causes, casual factors, and root causes. |

| |Based on the root causes identified, create a corrective action plan that generates a positive TCO (must |

| |identify the savings and costs for each recommendation made) for the customer with specific next |

| |steps/responsibilities for each action item. |

| |Step 5: Post Study |

| |Review immediate findings with customer document in a brief written or typed ESN Engineering Service Notice. |

| |Review finding with team members. |

| |Determine cause and effect and identify actual “Root Cause”. |

| |Check against known resources, OEM, EB internet resources. |

| |Develop test solutions. |

| |Offer steps to implement solutions to monitor performance. |

| |Write formal final RCFA Engineering Service Report for presentation to customer. |

| |Verify to whom results are reported. |

|Feedback about this SOP - Send to Field | |

|Engineering Advisor/Supervisor | |

DOCUMENTING YOUR WORK –

Documentation: The inspection results should be documented in an Engineering Service Notice or Engineering Service Report. TCO calculations that may apply are:

Revenue Enhancement: To determine the dollar impact a value-added event has on a customer’s revenues.

Asset Improvement: To evaluate the reduction in a customer’s asset base and the resulting reduction in possession costs for no longer being required to maintain that asset.

Process Improvement: To determine the reduction in the customer’s operating costs because of the reductions achieved in personnel requirements to perform specific tasks.

Expenditure Reduction: To help document the actions taken that have helped to reduce the customer’s total annual spend.

Special Services: To determine the value you added to your customer for the services you provide above and beyond the normal service requirements.
